Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Answer:

x = 17 cm

Step-by-step explanation:

Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem.  (a² + b² = c²)

First, plug the values into the equation:  (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)  

8² + 15² = c²

Square 8 and 15( or multiply them by themselves):

64 + 225 = c²

Add:  

289 = c²

Take the square root of both sides:  

√289 = √c²

Simplify:

17 = c

Therefore, x = 17 cm.
